Moroso 99-08 Harley-Davidson FLT/FLHT/FLHR/FLTR Spiral Core Wire Set - Black

This is a set of Moroso spiral core spark plug wires in black, designed for 1999-2008 Harley-Davidson FLT, FLHT, FLHR, and FLTR models. These wires are built to replace your stock ignition wires, helping to ensure a strong spark reaches your spark plugs for reliable engine operation.

The spiral core construction is a key feature here. It uses a conductive core wrapped in fiberglass and then covered with a high-temperature silicone boot. This design helps to reduce radio frequency interference (RFI) that can sometimes affect your bike's electronics, while still allowing for a robust spark. The black silicone outer jacket is durable and resists heat and abrasion, keeping the wires protected under the hood.
